Fortinet NSE6_FNC_AD-7.6 Dumps Questions Answers

The correct answer is B . In the trigger exhibit, the Filter Match setting is configured as Any 1 Filters , meaning the security trigger is satisfied when any one of the defined filters matches within the configured time window. The contractor triggers two of the defined filters, so two separate security events are generated because FortiNAC-F creates a security event whenever a security filter matches. The study guide confirms that each matched filter generates a security event, and when a trigger contains multiple filters, multiple matched filters can be associated with the resulting alarm.

The security rule exhibit also shows User/Host Profile: Match Contractors . Because the triggering user is a contractor, the user/host profile condition is satisfied. Once the trigger is satisfied and the user/host profile matches, FortiNAC-F generates a security alarm . The fact that Action is set to None does not stop the alarm from being generated; it only means no automated or manual response action is executed from that rule. Option A is wrong because the contractor profile matches, so an alarm is generated. Option C is wrong because only two filters were triggered, not three. Option D is wrong because two filters matched, so two events are generated, not one.

The exhibits show an enabled Security Rule using the SecurityTrigger , with the User/Host Profile configured as Match → Contractors . The associated trigger contains multiple security filters and uses Filter Match = Any . Because the endpoint in the scenario is a contractor, the User/Host Profile condition is satisfied.

The critical FortiNAC-F distinction is between a security event and a security alarm . The Study Guide states that a security event is generated whenever a security filter evaluates as true . Therefore, if the contractor triggers two security filters, two separate security events are generated .

The trigger is also satisfied, and because the Contractors profile matches, the security rule matches. A successful security-rule match generates one security alarm . The guide explicitly explains that a trigger can contain multiple filters and that each matched filter generates a security event; consequently, multiple events can be associated with a single alarm.

The exhibit ' s Action = None does not suppress alarm creation—it only means no response action is executed.

Therefore: 2 matched filters = 2 security events + 1 security alarm.

In FortiNAC-F, theSecurity Incidentsengine is used to automate responses to security threats reported by external devices. When an administrator wants to enforce a policy, such as quarantining contractors who access restricted websites, they must create aSecurity Rule. A Security Rule acts as the " if-then " logic that correlates incoming security data with the internal host database.

The documentation specifies that a Security Rule consists of three primary configurable components:

User/Host Profile:This identifieswhoorwhatthe rule applies to (in this case, " Contractors " ).

Trigger:This is theeventthat initiates the rule evaluation. In this scenario, the Trigger would be configured to match specific syslog messages or NetFlow data indicating access to prohibited websites. Triggers use filters to match vendor-specific data, such as a " Web Filter " event from a FortiGate.

Action:This defineswhathappens when the Trigger and User/Host Profile are matched. For this scenario, the administrator would select a " Quarantine " action, which instructs FortiNAC-F to move the endpoint to a restricted VLAN or apply a restrictive ACL.

While " Methods " (A) relate to authentication and " Security Strings " (E) are used for specific SNMP or CLI matching, they are not the structural components of a Security Rule in the Security Incidents menu.

" Security Rules are used to perform a specific action based on certain criteria... To configure a Security Rule, navigate toLogs > Security Incidents > Rules. Each rule requires aTriggerto define the event criteria, anActionto define the automated response (such as Quarantine), and aUser/Host Profileto limit the rule to specific groups.

In FortiNAC-F, theLayer 3 Network typeis specifically designed for deployments where the isolation networks—such as Registration, Remediation, and Dead End—are separated from the FortiNAC appliance ' s service interface (port2) by one or more routers. This architecture is common in large, distributed enterprise environments where endpoints in different physical locations or branches must be isolated into subnets that are local to their respective network equipment.

The reason the Configuration Wizard allows for more than one DHCP scope for a single isolation network type (state) is thatthere can be more than one isolation network of each typeacross the infrastructure. For instance, if an organization has three different sites, each site might require its own unique Layer 3 registration subnet to ensure efficient routing and to accommodate local IP address management. By allowing multiple scopes for the " Registration " state, FortiNAC can provide the appropriate IP address, gateway, and DNS settings to a rogue host regardless of which site ' s registration VLAN it is placed into.

When an endpoint is isolated, the network infrastructure (via DHCP Relay/IP Helper) directs the DHCP request to the FortiNAC service interface. FortiNAC then identifies which scope to use based on the incoming request ' s gateway information. This flexibility ensures that the system is not limited to a single flat subnet for each isolation state, supporting a scalable, multi-routed network topology.

" Multiple scopes are allowed for each isolation state (Registration, Remediation, Dead End, VPN, Authentication, Isolation, and Access Point Management). Within these scopes, multiple ranges in the lease pool are also permitted... This configWizard option is used when Isolation Networks are separated from the FortiNAC Appliance ' s port2 interface by a router.
